Description

Technical field[0001]The present invention relates to the technical field of fuel cells, in particular to a solid oxide fuel cell power generation system.Background technique[0002]A fuel cell is a chemical device that directly converts the chemical energy of the fuel into electrical energy, also known as an electrochemical generator. Solid Oxide Fuel Cell (SOFC) belongs to the third generation of fuel cell, which is an all-solid state that directly converts the chemical energy stored in fuel and oxidizer into electrical energy at medium and high temperatures. Chemical power plant. It is generally considered to be a fuel cell that will be widely used in the future like proton exchange membrane fuel cells. The solid oxide fuel cell power generation system is a clean and efficient energy conversion system that uses gaseous hydrocarbons such as natural gas or hydrogen and carbon monoxide as raw materials to convert chemical energy in the fuel into electrical energy. Relying on the widel...
